Product Description

Parallel idler with bracket:
I. Structural characteristics
Simple and regular: Mainly composed of multiple parallel idlers of the same specification and brackets. The idlers are cylindrical, with parallel axes. The structure is simple and clear, making it easy to install and maintain.
Uniform size: The diameter and length of the idlers are relatively uniform, ensuring the overall coordination and stability.

II. Performance characteristics
Stable support: Provides uniform and stable support for the conveyor belt, preventing the conveyor belt from sagging and excessive deformation. Especially suitable for horizontal transportation or transportation occasions with a small slope.
Low-friction operation: The surface of the idler is usually relatively smooth, and the friction coefficient with the conveyor belt is small. With high-quality bearings, the idler rotates flexibly, reducing running resistance, reducing power consumption, and improving the efficiency of the conveying system.
Strong wear resistance: Generally made of wear-resistant materials or specially treated, it can withstand long-term friction and pressure and has a long service life.
Good sealing performance: Effectively prevent dust, moisture and other impurities from entering the inside of the idler, protect key components such as bearings, and reduce the possibility of failures.

III. Characteristics of application scope
Widely used: Applicable to various types of belt conveyors and can play an important role in material transportation in industries such as industry, logistics, and mines. It can be used to transport various bulk materials such as coal, ore, grain, and building materials.
Adapt to different working conditions: It can work normally under different working environment temperatures, humidity and dust conditions, and has strong environmental adaptability. It also has good adaptability to changes in conveying speed and load.

IV. Maintenance characteristics
Convenient maintenance: Due to the simple structure, maintenance personnel can easily perform operations such as inspection, lubrication, and replacement of parts. Daily maintenance mainly includes checking the wear of the idlers, the running state of the bearings, and the tightness of the brackets.
Low cost: Compared with other complex conveying components, the maintenance cost of the parallel idler set is low. Its long service life and stable performance also reduce the operating cost of the entire conveying system.

The daily maintenance and upkeep of parallel idler sets can be carried out as follows:

Inspection
 

1. Regularly inspect the idlers for signs of wear and damage. Check the surface of the idlers for cracks, dents, or excessive wear. Look for any signs of deformation or misalignment.
2. Inspect the bearings for smooth rotation. Listen for any abnormal noises or vibrations. Check for excessive play or heat generation in the bearings.
3. Examine the brackets and mounting hardware for tightness. Ensure that all bolts and nuts are properly tightened and there are no signs of loosening or corrosion.

Cleaning
 

1. Keep the idlers clean by regularly removing dust, dirt, and debris. Use a soft brush or compressed air to clean the idlers and brackets. Avoid using harsh chemicals or abrasive materials that could damage the idlers.
2. Remove any accumulated material on the conveyor belt that could affect the performance of the idlers. This includes spilled materials, lumps, or foreign objects.

Lubrication
 

1. Lubricate the bearings according to the manufacturer's recommendations. Use the appropriate lubricant and apply it in the correct amount. Over-lubrication can lead to excessive heat generation and damage to the bearings.
2. Check the lubrication levels regularly and top up if necessary. Keep the lubrication ports clean and free from dirt and debris.

Adjustment
 

1. Check the alignment of the idlers with the conveyor belt. Adjust the position of the idlers if necessary to ensure proper contact and support. Use a straight edge or level to check for alignment.
2. Adjust the tension of the conveyor belt as needed. Ensure that the belt is not too loose or too tight. A proper tension will prolong the life of the idlers and the belt.

Replacement
 

1. Replace damaged or worn idlers promptly. Do not wait until the idlers are completely unusable as this can lead to further damage to the conveyor system.
2. Replace bearings when they show signs of excessive wear or failure. Use high-quality bearings and install them correctly to ensure smooth operation.

By following these maintenance and upkeep procedures, you can ensure the reliable operation and longevity of your parallel idler sets.
